6 Technical requirements
6.1 GeneralThe product shall be manufactured in accordance with the requirements of the relevant material standard and the applicable requirements of this technical specification. A manufacturing schedule shall be established and applied in accordance with EN 2078.
The product shall satisfy the requirements of the material standard and/or order and shall be free from irregularities prejudicial to the subsequent manufacture or use of this product. Notwithstanding previous acceptance complying with the material standard and this technical specification, any product that is found, at a later stage, to contain such discontinuities shall be rejected.
Unless otherwise specified, the requirements in Tables 1 and 2 shall apply in conjunction with those of the relevant material standard. Table 1 relates to lines 1 to 29 (inclusive) of the material standard and Table 2 relates to lines 30 onwards in which the sub-line format is also used. Lines 2 to 98 may also be opened in line 100 if the material standard details specific qualification requirements. If a specific line number is not shown in Tables 1 and 2, the requirement is stated in the material standard and/or order.
The requirements of the order and/or material standard shall over-ride the requirements of this technical specification.
6.2 Qualification requirements
See line 100 in Table 2 of this technical specification.
6.3 Release requirements 6.3.1 Release tests
Release testing shall be the responsibility of the manufacturer.
The purchaser reserves the right to perform any of the inspections and/or tests required by the material standard and/or order.
The test samples shall be representative of the product.
When required, the manufacturer shall inform the purchaser of the planned dates for extraction of samples and release testing in order that these operations may be witnessed.
Tables 1 and 2 detail the requirements for each line of the material standard. Unless otherwise specifically requested by the purchaser, a particular inspection and/or test for release shall be carried out if corresponding acceptance criteria and/or values are stated in the applicable material standard, but see also 6.3.5 "Capability clause".
6.3.2 Retests
If any requirement is not met and if the test procedure or test piece preparation is faulty, testing shall be re-applied at the original frequency after rectification of the original cause of failure on a test sample located near the original.
When failure cannot be attributed to faulty testing or test piece preparation, further test samples shall be selected at twice the original frequency from the product, 1 (one) of which shall be that on which the original results were obtained unless already withdrawn by the manufacturer after suitable identification of the cause of failure.
If all retest results are satisfactory, the batch shall be accepted. If 1 (one) or more tests are unsatisfactory, the batch shall be rejected.
